Referring to the drawings, A represents a rigid base-frame, which may be of the form shown or of any other suitable form adapted to sustain the operative parts hereinafter described.

B is a vertical tubular shaft or post fixed rigidly in the base-frame and rising therefrom to give support to the magazine 0 and other parts, as hereinafter explained.

The magazine 0 is preferably constructed, as shown, in the form of a hollow truncated cone with its base uppermost; but it may be made of cylindrical form, if preferred. This magazine consists of inner and outer parallel walls or plates 0, having in their proximate or inner faces a series of vertical grooves or channels to receive and guide the edges of the matrices D, as shown in Figs. 5, 1'3, and 14, which, being dropped into the upper ends of the grooves by the distributer, as hereinafter explained, are held in vertical columns,

one matrix resting 011 top of another, as shown in Fig. 5, each column containing matrices which bear the same character.

The magazine is constructed with arms or spokes extending inward to a central supporting hub or sleeve a, mounted upon and around the central shaft B and sustained thereon by a collar or shoulder 19, as seen in Fig. 5, so that the magazine as a whole, although standing normally at rest, may be revolved around the central shaft at the will of the operator in order to bring ope set of matrices or another over the assembling devices hereinafter described.

The inner and outer walls of the magazine are connected by intermediate ribs or distahcapieces 0 (Clearly shown in Figs. 13 and 14.) The magazine is constructed with a sufiicient number of vertical grooves to receive several sets or series of matricesin other words, the matrices representing a number of alphabets so thatthe magazine may carry at one time complete sets or series of matrices for producing two, three, or more sizes or styles of type characters.

At the lower inner edge of the magazine I mount at the foot of each matrix groove or channel an escapement E for releasing the matrices one at a time. This escapement consists of a centrally-pivoted lever having two projections 6 above and below its pivot, so that when vibrated it will have the effect of releasing the matrices one at a time. To each escapement is connected at the upper end a spring e, extending inward and attached to the frame of the magazine, so that it holds the escapement normally in position for thelower shoulder or lip e to engage under and sustain the lowermost matrix in the column. The manner in which these escapements are vibrated to discharge the matrices is clearly shown in Figs. 5 and 23. A series of finger-keys F, representing the various characters in a font, are pivoted to the front of the machine and extended rearward beyond their pivots and connected at their inner ends by links f to slides f, vertically guided in the frame and having their upper ends beveled to act on the correspondinglybeveled ends of the escapements E. When, therefore, the front end of the finger-key is depressed, its rear end causes the slide f to move the escapement and release a matrix, which falls out of the magazine. As soon as the finger-key is released the parts assume their original position and the next matrix in the magazine descends and takes the place of the one discharged.

The number and arrangement of the fingerkeys are such that they serve to operate the escapements of magazine-channels containing an entire font or set of matrices.

When the magazine is rotated by hand, as before referred to, one set of escapements is carried away from the actuating-slides f and another series of escapements, controlling a second set of matrices, is brought into operative relation to the slides. Thus it will be of escapements or another and to release matrices of one set or another, according to the position to which the magazine may be turned.

As there is nothing in the operation of the parts to turn the magazine, it will remain in the position in which it may be placed; but it will of course be understood that a latch or locking device of any appropriate character may be used to prevent its accidental rotation.

As the matrices are discharged from the magazine at dilferent points, provision must be made for receiving them and composing or arranging them in line. For this purpose I provide the stationary guide or channel G, fixed in position on the frame and arranged to deliver the matrices to an inclined traveling belt 6, sustained at its upper and lower ends by pulleys g, so that the matrices received 'upon this belt are carried downward and delivered one after another to the assembling devices, by which they are received and arranged in line in essentially the same manner as in the Mergenthaler machine. The matrices arriving at the lower end of the belt pass between horizontally-curved guideplates 9 (see Figs. 8 and 9,) and, continuing their downward course, they enter between two parallel sustaining-plates H, from and between which the matrices are suspended in line, as shown in Figs. 9, 10, and 11, the plates engaging the ears formed on the upper ends of the matrices, as shown in Figs. 11 and 16. These matrices, it will be observed, having ears projecting edgewise at both the upper and lower ends, are essentially the same as those used in the ordinary linotype. As the matrices descend one after another between the receiving-plates they are acted upon by the vertically-revolving wheel I, which pushes them forward one after another, thus forming a space for the entrance of the successive matrices and at the same time keeping the composed line in close order and pushing it forward to the left. The advance of the line is opposed by a yielding resistant consisting of a finger i, pivoted at t" to a horizontal slide t held normally in operative position by spring i attached to its upper end. The advance of the slide carrying the resistant is resisted bya spring 2' attached at one end to a piston or plunger i mounted to more to and fro in a horizontal dash-pot or cylinder i so that after the matrix-line has been released the spring will move the slide and detent to the rightin such position that the detent may cooperate with the next line composed. The piston and cylinder serve to check the speed of the parts and prevent the detent from returning too violently to its original position.

During the composition of the line it is necessary to introduce between the wordsthat is, between the matrices representing the last character of one word and the first character of the next-adjustable spaces, so that the line may be justified or elongated to a predetermined limit after all the matrices possible have been added. I make use of spaces consisting of a long and a short wedge re- Versely arranged and dovetailed together, so that after the space has been inserted in the line its thickness may be increased at the operative point by advancing the long wedge through the line past its companion in the manner described in the Mergenthaler patent, No. 345,525. These spaces J are stored in a magazine K on the outside of the main magazine, as shown in Figs. 1, 29, and 30, the

position of the magazine being such that.

when the foremost space is released it will descend into the holder or receiver immediately behind the last matrix in the line.

The magazine for the spaces consists, as shown in Figs. 29 and 30, of inclined top rails 7t and a similar pair of bottom rails 712 the spaces being supported vertically between the two pairs of rails, with the ears at their upper ends resting on the upper rails, as plainly shown in Fig. 30. The escape of the spaces is prevented by ears or lips at the lower ends of the upper rails. Their release is effected by means of a centrally-pivoted lifting-lever 76 connected at one end by a wire with a finger-key and arranged to act at the opposite end with a lifting effect on the lower end of the foremost space, so that when the space is thus lifted its upper end will pass clear of the ears on the rails 70, whereupon the space is free to pass downward from the rails to the matrix-line below. After the line of matrices and spaces has been formed as above described it must be brought into operative relation to the mold and clamped firmly into position against the same and the parts thereafter presented to the melting-pot in order that the mold may be filled with the metal to form the slug or linotype. These results are accomplished by the means shown more particularly in Fig. 1 and Figs. 18 to 22, inclusive.

L represents a horizontal bed or table arranged to revolve intermittingly around the vertical shaft B, motion being communicated thereto by studs Z on its under side engaging threads on the surface of a wheel or drum M, mounted on a horizontal shaftm in the main frame.

N represents the horizon tally-slotted mold in which the slug or linotype is formed. It is fixed rigidly in position on a post or standard n, rising from the table, so that the rotation of the table carries the mold in a circular path. The mold, as shown in Figs. '5, 11, 18, and 19, is in the form of a plate or block having a horizontal slot therethrough from front to rear of size corresponding to the body of thelinotypes to be produced. The front of the mold-slot being the side nearest to the center of the tab e is made open, as shown in Fig. 11, and of such form as to fit snugly against the edges of the matrices between their upper and lower cars, so that when the line of matrices is presented against the mold, as shown in Figs. 11, 21, &c., it will be closed thereby and the characters and matrices proper will stand in position to form the type characters in' relief on the edge of the linotype cast in the mold, asis usualin linotypemachines.

The rear end of the mold-slot, against which the base of the linotype is cast, is formed by the ejector-blade O,whicl1 is arranged to move forward and backward, being first retracted to and held in the position shown in Figs. 11, 21, &c., during the casting operation and thereafter advanced in due time to force the linotype out of the front of the mold. The blade is attached at its outer end to a head or plate 0 and is pushed normally backward by spiral springs o, encircling fixed rods 0 the outer ends of which are provided with adjustable nuts 0 which serve to limit the retreat of the plate, and thus to limit the depth of the mold-slot. and the height of the linotype or slug produced therein.

The advance of the ejector-blade to expel the slug is effected by a stationary rail or cam 0 (see Fig. 6,) connected to the main frame and having its inner curved surface formed with two steps or portions at different distances from the center of rotation. rotation of the table carries the ejector-head along the inside of the rail 0 it first acts to advance the ejector slightly in order that its forward edge may be projected beyond the mold, subject to the action of the trimming devices hereinafter described, after which the second portion of the rail acts to advance the blade until the slug or linotype is wholly ejected from the mold and permitted to fall therefrom into a galley or other receiver.

Previous to the casting operation it is necessary that the matrices in the line shall be forced edgewise tightly against the mold and also that the line shall be clamped endwise and kept within the predetermined length when the justifying wedges or spaces are actuated. This clamping action is effected by devices separately shown in Fig. 20 and also shown in Figs. 5, 11, 17, 21, and 33, in which P represents a horizontal slide or pressure device to act against the rear edges of the matrices and force them toward the mold, and P and P respectively, horizontal slides which advance on the slide P past the ends of the matrix-line in order to confine the line endwise. These three slides are mounted in a support p, fixed to the revolving table. They stand directly opposite the mold and are each provided in the rear end with a roller p. These rollers are acted upon, respectively,

at the proper time by cams 19 p and p fixed As the composed line of matrices suspended between the plates or rails H the slides P and. P are drawn back from the mold, as shown in Fig. 33, so that as these parts continue their advance the matrices will pass between the mold N on one side and the slide P on the other until the slide P at the rear encounters the matrix-line, when it acts to push the line forward to the left out of the holding plates or rails H. As soon as the partshave advanced sufficiently in their circular path the slide P moves forward in front of the matrix-line, which at this period is clamped or confined in one direction between the slide P and the mold N and in the opposite direction between the slides P and P, the slide P in the meantime advancing until the matrices are forced tightly against the mold. While thus confined the matrix-line is carried forward by the rotation of the table until the mold reaches the casting position directly over the mouth of the melting-pot Q, when the movement of the table is arrested. This pot Q is mounted on a trunnion q in the upper ends of swinging standards q, mounted on horizontal pivots at their lower ends. A spring (1 connected to the lower end of the pot, tends to draw it backward or outward and also to tip its delivery-mouth downward away from the mold, which passes thereover. The pot is of essentially the same construction as those ordinarily used in linotype-machines, having a mouth or spout through which the metal is delivered and an internal pumpplunger 1 to effect the delivery of the metal. The mouth instead of being arranged to deliverhorizontally, as usual, is turned upward to fit into a recess in the under side of the mold and is arranged to deliver the metal vertically through openings 01, Figs. 18, 19, and 21, in the under side of the mold. While the mold is at rest in the casting position the mouth of the pot is closed tightly into its under side and the pump-plunger actuated to fill the mold with metal and produce the linotype, which it'will be observed is cast within the slot of the mold between the ejector-blade and the matrices. The movements of the pot are effected, as shown in Figs. 2, 6, 17, 21, and 22, by two cam-surfaces g and 1 carried on the side face of the vertical gearwheel g and arranged to engage, respectively, with rollers g and g attached, respectively, to the mold-supporting standard and to the melting-pot. The cam 11 first swings the standard and the pot forward until the mouth of the latter is beneath the mold, after which .the cam g acts to tip the pot and force its mouth upward into the mold. After the casting action the cams release the pot, which falls back into its original position.

Before the casting action occurs the justification of the line must be effected by lifting the wedge-spacers J therethrough. This is effected, as shown in Figs. 21, 22, and 24,

by the pressure-plate R, supported at its ends by rods r, resting on spiral springs r in vertically-movable rods r mounted in the revolving table L and connected at their lower ends by a bar r which is mounted on its under side and arranged to override a fixed roller 4, which acts to lift the bar and through the intervening parts apply an upward pressure to the plate R, which forces the spacers upward through the line immediately before the operation of the metal-delivering pump. The pump-plunger g is actuated, as shown in Figs. 2, 17, 21, and 22, by a lever pivoted at an intermediate point in its length to the pot-supporting standard and provided at the outer end with a roller acted upon at the proper time by a cam on the outer end of the horizontal shaft-carrying wheel g After the casting action and after the retreat of the pot the table continues its rotation, carrying the matrix-line forward to a lifting device S, by which the entire line, including spaces, is lifted to the top of the machine for presentation to the distributing mechanism hereinafter described. As shown in Fig. 5, this lifting device S, which slides upward and downward in guide 3, is constructed with the two depending jaws s and 8 having at their lower ends lips or flanges to underride the ears of the matrices,which are at all times exposed above the level of the mold and clamp. As the table revolves to carry the line of matrices and spaces forward into the elevator S the main clamping-slide P slowly retreats,and in due time the end slides P and P are also retracted,thus leaving the line of matrices in the elevator, while the mold and clam ping devices continue their course. \Vhile the slides are all retracted, so as to leave an open space in front of the mold, the ejector is slightly advanced and the edge of the slug protruded beyond the face of the mold, as hereinbefore explained. l/Vhile the slug is thus sustained in and carried forward by the mold its forward edge is acted upon by a rotary trimmer T, (shown in Figs. 2, 5, 6, 26, and 27,) which serves to remove those slight burs, fins, or

, projections which are sometimes formed between the face of the mold and the edges of the matrices when the parts are not kept clean. The trimmer consists of two millingcutters f, carried by a vertical spindle and having cutting-teeth on their proximate faces, so that they will dress the opposite edges of the slug passed between them, as shown in Fig. 27. After the slug is carried beyond the trimmer the ejector-blade completes its advance and the slug or linotype falls from the machine.

As it will be a common practice to use interchangeable molds, producing slugs of different thicknesses, it is desirable to make the trimming device adjustable. To this end the lower cutter i is fixed on the lower end of the spindle '15, mounted in bearings and secured against end motion. The upper cutter is mounted on a sleeve surrounding the spindie if and connected thereto by a spline or feather. This sleeve 25 revolves in and is fixed against end motion in a supporting-box i having an external screw-thread seated in the main frame, so that the rotation of this box serves to raise and lower the sleeve 25 and the upper cutter in relation to the lower cutter. The adjustment is effected by means of a lever f fixed to the sleeve and provided with a latch or locking device which engages a toothed sector 15.

During the casting operation and while the table is at rest it is locked firmly in position, as shown in Figs. 2, 5, and 6, by a-revolving plate Z mounted on a horizontal shaft and arranged to enter a notch-gear on the side of table shown at Z Fig. 6.

The distributing mechanism, located at the upper end of the magazine, is shown in Figs. 1, 2, 3, 4, 5, and 25. The matrices (shown in Fig. 16) are each constructed at the upper end with a notch or indentation, having in the edges teeth by means of which the matrices are suspended while traveling along a distributor-bar of corresponding form. The teeth of matrices bearing a given character or letter are alike in number and arrangement; but the teeth are varied in number or arrangement, or both, for matrices bearing different characters, and the teeth of the dis tributer-bar are correspondingly varied at different points in its length, so that each matrix will be suspended by its teeth in the course of its travel until it reaches a point directly over its appropriate channel in the magazine, at which point its teeth will bear such relation to those of the bar that it is permitted to escape and fall into the magazine. This construction of the matrices and the distributer-bar may be in all respects identical with those set out in the Mergenthaler patent, No. 347,629, dated August 17, 1886, eX- cept that in the present instance the distributer-bar, instead of being straight, is curved in a circular path to correspond with the form of the magazine.

U represents the fixed distributor-rail, supported on the top of the magazine and of sufficient length to cover one section of the magazine-that is to say, the portion of the magazine containing one set or series of matrices. The matrices of the different sets are alike as to their combinations of distributing-teeth, so that the matrices in use will be delivered into that particular section of the magazine which stands for the time being under the rail. It will be understood that the turning of the magazine which brings one set or another of matrices into action also brings the channels containing them under and in operative relation to the distributer-rail. Thus the one rail is made to distribute at different times different sets of matrices into their appropriate portions or sections of the magazine.

It will be observed that the distributer-rail is carried outward eccentrically at its receiving end, so that when the line of matrices and spaces is lifted by the elevator S, before re- IIO ferred to, the line will stand adjacent to the end of the rail and in such position that when moved laterally the teeth of the matrices will engage the teeth of the rail in order that they mayhang therefrom. Forthepurposeofthus carrying the line out of the elevator onto the rail I provide a series of horizontally-revolving arms V, pivoted to a skeleton plate c on the upper end of a central shaft 1), which extends downward through the main shaftB of the machine, its lower end being provided with a worm-wheel 1: receiving motion from a worm The arms V, as shown in Fig. 3, are pivoted at c and connected to the springs u which tend to draw them forward, so that in the course of their revolution they act successively against the matrices in the elevator S, carrying them forward out of the elevator to the distributer-rail and urging the line forward in compact form along the rail.

In order to insure the delivery of the matrices from the rail at the proper points and to prevent them from clinging together, it is desirable to separate them before they pass upon the distributing portion of the rail and to keep them separated as they advance. To this end I adopt the construction shown more particularly in Figs. 2, 3, 4, 5, and25, in which WV represents an escapement device or stop located beneath the distributor-rail in position to encounter the foremost matrix of the line, so as to prevent the line as a whole from advancingfarther. This escapement consists, as shown in Fig. 25, of a horizontalstop-finger 10, arranged to slide inward and outward and connected through an intermediate lever to with a second stop-finger to, also arranged to slide inward and outward. A spring 10 holds the finger to normally in an inward position to arrest the foremost matrix in the line,while the second finger 10 is retracted and stands in position to advance in front of the next succeeding matrix. When the finger w is pushed forward to release the foremost matrix, the finger w advances and in turn checks the advance of the line. Thusit will be seen that the alternating movement of the two fingers serves to release the matrices one after another from the end of the line,the line being, however, urged forward and held in compact order by the pressure of the followingarm V.

For the purpose of actuating the escapement and moving the released matrix forward along the distributer I mount in the revolving plate or frame r, before mentioned, a series of radially-sliding carrier-fingers X, each having a shank surrounded and urged outward by aspiral spring. Each of these fingers is notched or slotted at the outer' end in ordertoembraceasinglematrix. Asthe fingers are moved forward by the rotation of the carrier-frame their outer ends ride against the inside of a stationary rail whereby they are held backward away from the line of matrices, as clearly shown in Figs. 3 and 4:. The rail x terminates slightly in advance of the escapement XV. As each finger X passes the end of the rail itis thrust outward, so as to actuate the escapement and release the forward matrix, which is at the same instant embraced by the finger, which carries it forward along the distributer to the point at which it is released by the latter.

It will be understood from the foregoing that the fingers X operate successively on the escapement, each one effecting the release of a matrix from the line and carrying the matrix forward until it is in position to fall into its appropriate channel in the magazine. As each carrier-arm V reaches the escapement device its spring yields and permits it to swing inward in order to pass the escapement.

The elevator S for lifting the matrices to the magazine slides upward and downward in the fixed guide 8, being raised and lowered by a chain 5 passing over a pulley and provided at its outer end with a counterweight sufficient to lift the elevator when the parts are released. When the elevator S is down, it is held in position by an angular latch 5 pivoted thereto and engaging the guide. When the table in its revolution presents the matrix-line within the elevator, it encounters the latch s and, disengaging the same, permits the elevator to rise under the influence of the weight.

In order to elfect the lowering of the elevator after the matrices have been carried therefrom to the distributer-rail, I provide the shaft of wheel 3, as shown in Figs. 2, 3, and 5, with a beveled pinion s engaging pinion s on the shaft of asecond pinion 3 arranged to engage successively the several racks or groups of teeth 8, formed on top of the contin uously-revolving frame or plate 1 heretofore referred to. The several racks are separated by untoothed surfaces, as shown. After the matrices are delivered from the elevator one of the racks engages the pinion s and through the intermediate parts turns the wheel 5 in a proper direction to lower the elevator S. During the periods when the blank surfaces are passing the pinion s the elevator is permitted to remain at rest in its lowest position to receive the matrices and thereafter to ascend and deliver the matrices before the next rack comes into action. During the descent of the elevator the pinion s and its connections maybe permitted to turn in a reverse direction, or a clutch 5 con trolled by a lever 8 acted upon by the rising elevator, may be used to disconnect the pinion s for the time being. These details, which may be variously modified, are not of the substance of my invention.

The wedge-spaces carried upward with the matrix-line are constructed, as usual, without distributing-teeth, and consequently theyare released as soon as they leave the elevator. Being thus released, they fall into a conductingtube or chute Y, which extends downward around the outside of the magazine or holder K, heretofore described.

Movement may be imparted to the various parts of the machine by driving mechanism of any appropriate character; but I prefer to employ the arrangement of parts represented in the drawings.

The matrix assembling wheel I, commonly known as the star-wheel, receives motion as shown more particularly in Figs. 6,7, and 8, its shaft 2' having a pulley 2 which receives motion by belt from a pulley 2 on a shaft carrying abeveled pinion 1' driven from pinion t on a shaft 1' which receives motion in turn through abelt and pulleys from the shaft 2', driven in turn by a belt 2' and pulleys from the main shaft on. The shaft 2' also communicates motion through a belt and pulleys to the vertical shaft of the trimmer T, as shown in Fig. 6.

The assembling-belt g, to which the matrices descend from the magazine, receives motion through its upper supporting-pulley 9, (see Figs. 1 and 2,) its shaft in turn carrying a pulley driven by belt 9 from apullcy on shaft g which is in turn connected through a belt 9 and pulleys to shaft f at the base of the machine, the last named shaft being also provided, as shown in Figs. 1 and 5, with the worm r for imparting motion to the central vertical shaft of the machine.

Power is communicated to the machine through the main shaft in, provided with the pulleys m and m the latter being constantly ,driven and serving, through its small side pulley and belt to communicate a constant motion to the assembling and trimming devices. The pulley 'm. cooperates with a friction-clutch m at its side, so that when the clutch is thrown into engagement with the pulley motion will be communicated to the shaft m, and thence to the large wheel M, for the purpose of giving the intermitting rotation to the table in order to effect successively the operations of taking the assembled line from the composing devices, clamping the line to the mold, presenting the mold to the melting-pot, delivering the matrix-line to the elevator, partly ejecting the sing and withdrawing the matrix-clampin g devices in order to expose the slug for the action of the trimmer, presenting the edge of the slug to the trimming devices, the slug from the mold.

The throwing of the clutch into action is effected, as shown in Figs. 1, 2, 6, 31, and 32,

and finally ejecting by means of a rock-shaft m having at one end a forked arm m to move the clutch and at the opposite end an arm m standing adjacent to the cam-wheel m on the shaft 9 A verticallymovable roller m carried by lcver m is connected with a vertically-moving finger-key m so that when this key is depressed the roller hi will be lowered between the cam-wheel m and arm in, whereupon the cam, pushing the roller laterally, will actuate the crank-arm m and actuate the clutch, which will in due time by the rotation of the wheel m be automatically released.

I am aware that ina type-composing machine two rows of magazine-tubes have been arranged to slide in relation to typeejecting devices so that one row of tubes or the other could be brought in operative relation to said ejecting devices at will, and this I do not claim, my invention contemplating a magazine which is movable or reversible around the center of motion.
